BACKGROUND OF THE INVENTION

1 . Field of the Invention

The present invention relates to a manufacturing method of a solid-stateimaging apparatus, such as a charge coupled device (CCD) and acomplementary metal oxide semiconductor (CMOS), a solid-state imagingapparatus, and an electronic imaging apparatus mounted with thesolid-state imaging apparatus.

2 . Description of the Related Art

A dual inline package (DIP) and a small outline package (SOP), each madeof a ceramic or a resin material, have been widely used as aconventional solid-state imaging apparatus.

A conventional solid-state imaging apparatus is configured so that theelectrodes of a solid-state imaging device and the lead frames formed ona package are bonded together with bonding wires, such as Au lines.Moreover, a light transmitting member is made to adhere to a packagesurface on the light receiving surface side of the solid-state imagingdevice. It is required for an electronic imaging apparatus, such as adigital camera and a video camera, using this sort of solid-stateimaging apparatus to perform an adjustment of a relative positionalrelation between the solid-state imaging device and an opticalviewfinder, and an adjustment of the position of the solid-state imagingdevice in relation to focusing at the time of assembling the electronicimaging apparatus.

In this adjustment, the following adjustments are necessary: (1) theadjustment of positioning in focusing direction, (2), (3) theadjustments of up, down, left, and right tilts for the prevention ofpartial blurring, (4), (5) the adjustments in horizontal and verticaldirections for field angle adjustment, and (6) tilt and rotationadjustments.

Consequently, at least the adjustments of six axes are needed. One ofthis sort of solid-state imaging apparatus is disclosed in U.S. PatentPublication No. 2003-0025824 and Japanese Patent Application Laid-OpenNo. 2000-333050.

SUMMARY OF THE INVENTION

The conventional solid-state imaging apparatus is required to performthe six axis adjustment at the time of being incorporated into anelectronic imaging apparatus to every solid-state imaging apparatus, andthe adjustments are a step taking a very long operation time.Consequently the cost of the electronic imaging apparatus itself ispushed up.

In the first place, a factor of the necessity of the six axis adjustmentresides in a die bonding step of making the solid-state imaging deviceadhere to the package and fixing it thereto. That is, the factor residesin the limitations of the horizontal resolution, vertical resolution,and rotational resolution of the head of a die bonding apparatus tocause the dispersion of the positions of the solid-state imagingapparatus in the horizontal, vertical, and rotational directions.

Another factor resides in the occurrence of the dispersion of focus inthe depth direction and the dispersion of up, down, left, and righttilts of a mounted solid-state imaging device owing to the factors of anindividual difference of the size of a package itself, a bend of the dieattaching surface of the package, on which a solid-state imaging deviceis placed, and the like.

It is an object of the present invention to provide a manufacturingmethod of a solid-state imaging apparatus, a solid-state imagingapparatus, and an electronic imaging apparatus, each capable ofeliminating the need of the six axis adjustment taking a long operationtime at the time of incorporating the solid-state imaging apparatus intothe electronic imaging apparatus to enable the simple and no-timerequiring assembly of the solid-state imaging apparatus.

An aspect of the present invention is a manufacturing method of asolid-state imaging apparatus comprising steps of: preparing asolid-state imaging device having a light receiving region at a mainsurface thereof; preparing a light transmitting member having an areafacing the main surface of the solid-state imaging device, and anextending portion extending from the area facing the main surface;preparing a holding member having a space for holding the solid-stateimaging device therein, and having a positioning portion for positioningthe solid-state imaging device; fixing the light transmitting member tothe main surface of the solid-state imaging device in parallel to eachother to keep a constant interval therebetween; bringing a side of thesolid-state imaging device to meet the positioning portion of theholding member; and fixing the extending portion of the lighttransmitting member to the holding member.

According to the present invention, the operations of the six axisadjustment, which have been necessary at the time of incorporating asolid-state imaging apparatus into an electronic imaging apparatus, canbe rendered unnecessary. Consequently, the assembly operation of thesolid-state imaging apparatus can be made remarkably simple, and theelectronic imaging apparatus can be manufactured at a low cost.

DESCRIPTION OF THE EMBODIMENTS

In the following, exemplary embodiments for implementing the presentinvention will be described in detail with reference to the attacheddrawings.

FIG. 1 is a plan view illustrating an embodiment of a solid-stateimaging apparatus according to the present invention. FIG. 2 is anexploded perspective view illustrating each part constituting thesolid-state imaging apparatus in an exploded state. FIG. 3A is asectional view taken along the line 3A-3A of FIG. 1, and FIG. 3B is asectional view taken along the line 3B-3B of FIG. 1. FIG. 3A illustratesthe bonding portion of the solid-state imaging device with a wiringsubstrate in detail.

In FIGS. 1 to 3B, a light receiving region 101 a is formed on a mainsurface of a solid-state imaging device 101, such as a CCD or a CMOS.Electrodes 101 b contributing to input and output signals of thesolid-state imaging device 101 are formed in regions of the peripheralportions of the light receiving region 101 a of the solid-state imagingdevice 101 over both of the opposing sides thereof. A light transmittingmember 103 is arranged over the upper surface of the solid-state imagingdevice 101. As the light transmitting member 103 bonded to thesolid-state imaging device 101, mainly glass or crystal is used, and thelight transmitting member 103 is arranged over the light receivingsurface of the solid-state imaging device 101 with a constant intervalbetween them.

As the method of arranging the light receiving surface of thesolid-state imaging device 101 and the light transmitting member 103 inparallel to each other with the constant interval between them, noespecial limitations exist. For example, as illustrated in FIGS. 3A and3B, there is a method of using spherical spacers 106. Moreover, it canbe easily realized to arrange the light receiving surface of thesolid-state imaging device 101 and the light transmitting member 103 inparallel to each other with the constant interval between them by usingcolumnar spacers (not illustrated).

Furthermore, by making an adhesive 107 intervene in the surroundings ofthe spacers 106, the solid-state imaging device 101 and the lighttransmitting member 103 can be easily made to adhere to each other withthe constant interval kept between them. The spacers 106 and theadhesive 107 are uniformly formed over four sides of the solid-stateimaging device 101, and are arranged lest they should enter the lightreceiving region 101 a of the solid-state imaging device 101.

In the configuration described above, the solid-state imaging device 101and the light transmitting member 103 are arranged in parallel to eachother with the constant interval between them, and consequently both ofthe parallelism between the light receiving surface of the solid-stateimaging device 101 and the light transmitting member 103 and thedistance between the light receiving surface of the solid-state imagingdevice 101 and the light transmitting member 103 can be secured to beconstant. The light transmitting member 103 is structured to make atleast a part thereof extend from the solid-state imaging device 101.That is, it is important to form at least a part of the lighttransmitting member 103 to be larger than the size of the solid-stateimaging device 101. By extending at least a part of the lighttransmitting member 103 in this way and by using the extending part forbonding the light transmitting member 103 with a holding member 102,described below, the positional accuracy of the light transmittingmember 103 can be easily secured.

Moreover, the whole of the light transmitting member 103 may be largerthan the solid-state imaging device 101. In this case, the size of thelight transmitting member 103 on the sides of both the opposing sides ofthe light transmitting member 103 on which sides the electrodes 101 bare not formed on the solid-state imaging device 101 is preferably madeto be larger than the size of the solid-state imaging device 101 if theelectrodes 101 b are formed on both of the opposing sides of thesolid-state imaging device 101 as illustrated in FIGS. 1 and 2.Moreover, the light transmitting member 103 is more preferably shaped tosituate its end faces between the electrodes 101 b of the solid-stateimaging device 101 and the light receiving region 101 a on the sides ofboth of opposing sides on which the electrodes 101 b are formed.

By shaping the light transmitting member 103 in this shape, theelectrodes 101 b are exposed after the light transmitting member 103 hasbeen arranged over the solid-state imaging device 101, and consequentlywiring substrates 104 can be attached after the adhesion of the lighttransmitting member 103. It is no doubt possible to attach the wiringsubstrates 104 before the arrangement of the light transmitting member103, but by arranging the light transmitting member 103 beforehand, thetime during which the solid-state imaging device 101 is exposed to theassembling environment can be shortened. Consequently, particles and thelike that adhere to the light receiving region 101 a of the solid-stateimaging device 101 can be prevented.

The thickness of the light transmitting member 103 is not especiallylimited, but the thicknesses from 0.1 mm to 2.0 mm are suitably used.Each of the wiring substrates 104 is made of a flexible printed circuitboard of the structure in which a conductive foil 104 c made of Cu orthe like is laminated on a base film 104 e made of polyimide or the likeand the conductive foil 104 c is protected by being covered by aninsulator 104 d , such as solder resist, except for a terminal portionand a soldering portion as illustrated in FIG. 3A.

Inner leads 104 a wired at the same pitches as those of the electrodes101 b formed on the solid-state imaging device 101 are formed on theconductive foil 104 c, which is electrically bonded to the electrodes101 b of the solid-state imaging device 101, as illustrated in FIG. 2.Outer leads 104 b are formed on the outer side of the wiring substrate104, where electrical bonding to a not illustrated substrate of anelectronic imaging apparatus body is performed.

Stud bumps 108 made of Au or the like are formed on the electrodes 101 bformed on the solid-state imaging device 101 for bonding the electrodes101 b with the inner leads 104 a of the wiring substrate 104 asillustrated in FIG. 3A. It is preferable to perform planarizationprocessing to the upper surfaces of the stud bumps 108 in order to makethe bonding of the stud bumps 108 with the inner leads 104 a easy. Afterthe relative positions of the stud bumps 108 to the inner leads 104 ahave been adjusted, the electrodes 101 b and the inner leads 104 a areelectrically bonded together by gang bonding, single point bonding, orthe like.

After the light transmitting member 103 and the wiring substrates 104have been attached to the solid-state imaging device 101, the holdingmember 102 is attached to the solid-state imaging device 101. Theholding member 102 has a space 102 d capable of holding the lighttransmitting member 103 therein and at the same time holding thesolid-state imaging device 101 therein as illustrated in FIG. 2.Moreover, the holding member 102 is a part having positioning portions102 a for positioning the solid-state imaging device 101. In thefollowing, the holding member 102 will be described in detail.

As illustrated in FIG. 2, the holding member 102 is a plate-like memberforming the space 102 d capable of holding the solid-state imagingdevice 101 therein at the center of the holding member 102. Thepositioning portions 102 a are formed on the holding member 102. Thepositioning portions 102 a are integrated with the holding member 102,and are provided at three points of the holding member 102 so as to beprojected into the space 102 d as protrusions.

As a material for forming the holding member 102, a material havingrigidity and being realizable of the dimensional accuracy of, forexample, ±50 μm or less is suitable. Also as to the planarity of thematerial, the one realizable the processing accuracy of ±30 μm or lessis suitable. More suitably, the planarity is ±10 μm or less. As thematerials capable of acquiring these characteristics, the materials,such as plastic and metal, can be suitably selected.

In the case of plastic, the materials having rigidity are suitable, andfor example, polycarbonate (PC), acrylonitrile butadiene styrene (ABS),POW, polypropylene (PP), polyethylene (PE), and PPEE are suitable.However, the materials are not limited to those listed in the above.Moreover, it is preferable that the materials have conductivity from thepoint of view of electro-static destruction.

In the case of metal, as the quality of material, for example,iron-nickel alloys, such as 42 alloy, 50 alloy, permalloy, Kovar, andInvar, and stainless steel, such as, stainless steel (SUS) 430, and SUS304, are suitable, but the metals are not limited especially to theabove-listed ones. It is also possible to suppress the surface roughnessand the planarity to a desired extent or less by performing grinding,lapping, or the like, after a desired shape has been acquired by pressworking. In case of using a metal material, because the metal materialhas high conductivity, the influences of electro-static destruction canbe prevented that much at the time of contact with the solid-stateimaging device 101, and the metal material is more suitable.

The solid-state imaging device 101 and the light transmitting member103, which are arranged in parallel to each other as described above,are attached to this holding member 102. The attachment method is tobring the side of the solid-state imaging device 101 to the positioningportions 102 a (the positioning portions 102 a at three positionsillustrated in FIG. 2 in the present embodiment) to meet the side to thepositioning portions 102 a . At the same time, bonding is performed withthe adhesion surface side of an extending portion of the lighttransmitting member 103 to the solid-state imaging device 101 close tothe holding member 102 (see FIG. 3B). In this case, as illustrated inFIGS. 3A and 3B, the light transmitting member 103 may be made to adhereto the holding member 102 with a sealing resin 105, or the lighttransmitting member 103 may be made to adhere to the holding member 102with an adhesive separately.

By adopting this configuration, the light transmitting member 103 can beattached to the holding member 102 in parallel to it. Because the lighttransmitting member 103 and the solid-state imaging device 101 havealready been bonded together in parallel to each other, the position(position in focusing direction) of the solid-state imaging device 101to the holding member 102 can be made to be constant. Moreover, thepositions of the up, down, left, and right tilts can be made to bealways constant in order to preventing partial blurring.

That is, by bonding the light transmitting member 103 and thesolid-state imaging device 101 together on the basis of the holdingmember 102 while keeping the light transmitting member 103 and thesolid-state imaging device 101 in parallel to each other, the adjustmentof the position of the solid-state imaging device 101 to the holdingmember 102 in the focusing direction (Z direction) . . . (1) iscompleted. At the same time, the adjustments of the three axes of theup, down, left, and right tilts . . . (2), (3) are completed.

Furthermore, since the bonding of the solid-state imaging device 101 tothe light transmitting member 103 is performed by contacting the side ofthe solid state imaging device 101 bonded to the light transmittingmember 103 with the positioning portions 102 a formed on the holdingmember 102 (bringing the side to meet the positioning portions 102 a),the positions of the solid-state imaging device 101 to the holdingmember 102 in the horizontal and vertical directions and in the tilt androtational directions can be always made to be constant. That is, theadjustments in three axes in the horizontal and vertical directions (Xand Y directions) . . . (4), (5), and the rotational direction (θ) . . .(6) can be completed. These adjustments in the six directions (1)-(6)are the same as those described in the clause of Description of theRelated Art.

At this time point the structure of the present invention is in thestate in which all of the six axis adjustment of the solid-state imagingdevice 101 to the holding member 102 have been completed. Moreover, itis desirable to form a fixing unit including at least a holding hole inthe holding member 102. Moreover, one or more positioning holes may beformed in the holding member 102 in addition to the holding hole.

Positioning holes 102 c and holding holes 102 b are formed in theholding member 102 as illustrated in FIGS. 1 and 2 in the presentembodiment, which is an example of the formation of two positioningholes 102 c and three holding holes 102 b . These holes can be formed inthe holding member 102 accurately by publicly known drilling orpunching.

Consequently, the position of the solid-state imaging device 101 can beuniquely determined to the positions of the holding holes 102 b of theholding member 102, and the solid-state imaging apparatus always keepinga fixed state positional relation can be provided.

Moreover, the fixing unit (holding holes 102 b) is formed on the side ofthe solid-state imaging apparatus, and the bonding portion (holdingholes or the like) corresponding to the fixing unit is accurately formedon the side of the electronic imaging apparatus, such as a digitalcamera and a digital video camera. By the formation of these fixingunits and bonding portion, desired accuracy of the solid-state imagingapparatus to the electronic imaging apparatus can be easily acquiredonly by bonding the solid-state imaging apparatus of the presentinvention to the electronic imaging apparatus by the use of the fixingunit.

At this time, as described above, the six axis adjustment of thesolid-state imaging device 101 to the holding member 102 have beencompleted. Consequently, by incorporating the solid-state imagingapparatus of the present invention into the electronic imaging apparatusby the use of the fixing unit (holding holes 102 b) formed in theholding member 102, the solid-state imaging apparatus can be simplyincorporated without performing the six axis adjustment.

The sealing resin 105 illustrated in FIGS. 3A and 3B is formed to coverthe outer periphery of the spacers 106 and adhesive 107 here. Moreover,although it is not illustrated, the sealing resin 105 may be formed tocompletely cover the back surface (non-light receiving surface side) ofthe solid-state imaging device 101. The sealing resin 105 is, forexample, the one made of an epoxy resin having an excellent moistureresistance, and no limitations to the sealing resin 105 existespecially. But a sealing resin of the type of being cured by heat, anultraviolet ray, or concomitant use of both of them is suitable.

By forming the sealing resin 105 in such a way, the moisture resistanceof the solid-state imaging device 101 and the reliability of themechanical and electrical bonding of the conductive foil 104 c , whichis a bonding portion member, can be improved. As a unit covering theback surface of the solid-state imaging device 101, a protecting member112 (illustrated in FIG. 4) may be made to adhere to the back surface inaddition to the method of using the sealing resin 105.

FIG. 4 is a sectional view illustrating an embodiment covering the backsurface (non-light receiving surface side) of the solid-state imagingdevice 101 with the protecting member 112. In FIG. 4, the same parts asthose in FIGS. 1 and 2 are denoted by the same reference characters asthose of FIGS. 1 and 2. The material of the protecting member 112 is notespecially limited, but, for example, iron-nickel alloys, such as 42alloy, 50 alloy, permalloy, Kovar, and Invar, and stainless steelmetals, such as SUS 430 and SUS 304, each having high thermalconductivity, are suitably used. By using the material having the highthermal conductivity, the material can also assume the role of aradiator plate.

Moreover, although the protecting member 112 is made to adhere to theholding member 102, it is preferable to make the back surface of thesolid-state imaging device 101 adhere to the protecting member 112 bythe use of an adhesive having high thermal conductivity in the case ofaiming both of the protection and heat radiation of the solid-stateimaging device 101.

Although the solid-state imaging apparatus of the present invention issometimes fixed to an electronic imaging apparatus by being directlyattached thereto, the similar advantages can be acquired also byattaching the solid-state imaging apparatus to another unit part onceand then by fixing solid-state imaging apparatus to the electronicimaging apparatus by fixing the unit part thereto. Although the unitpart is not especially limited, for example, a unit part including anoptical part, such as an optical low-pass filter, mounted on thesolid-state imaging apparatus of the present invention can be given.

FIG. 5 illustrates an example of a unit (hereinafter referred to assolid-state imaging unit) including an optical part, such as the opticallow-pass filter, placed on a solid-state imaging apparatus. In FIG. 5,the same parts as those illustrated in FIGS. 1 to 4 are denoted by thesame reference characters as those of FIGS. 1 to 4. In FIG. 5, theoptical low-pass filter 409 is mounted on the solid-state imagingapparatus of the present invention. The solid-state imaging unit 410includes the solid-state imaging apparatus and the optical low-passfilter 409. The filter 409 includes an infrared cut filter composed ofan infrared absorbing glass and a dichroic mirror, and a low-pass filtercomposed of a separating plate separating a subject image into ahorizontal direction and a vertical direction and a phase plate.

The optical low-pass filter 409 is fixed to an optical low-pass filterholding member 411, in which holding holes 411 a are formed at thepositions corresponding to the holding holes 102 b formed in thesolid-state imaging apparatus.

The optical low-pass filter holding member 411 equipped with the opticallow-pass filter 409 is bonded to the solid-state imaging apparatus byadjusting the relative positions of the holding holes 102 b and 411 a onthe basis of the holding member 102 of the solid-state imagingapparatus. By forming the optical low-pass filter holding member 411with accuracy, a fixed state positional relation between the solid-stateimaging apparatus and the optical low-pass filter 409 can be held in thesolid-state imaging unit 410.

FIG. 6 is a view illustrating an example of incorporating thesolid-state imaging unit 410 illustrated in FIG. 5 into a camera(electronic imaging apparatus). In FIG. 6, the same parts as those inFIG. 5 are denoted by the same reference characters as those in FIG. 5.In FIG. 6, the camera includes a camera body 513, a shutter unit 514,and a mirror 515, which is obliquely provided in the imaging path orwithdraws therefrom according to an observation state and an imagingstate, respectively.

In the observation state, the mirror 515 is in the state of beingobliquely provided in the imaging optical path, and advances a lightbundle reflected on the mirror 515 toward the upper part of the camerabody 513. The reflected light bundle passes through a penta-prism 516and a finder optical system 517 to enable an observation image to beobserved on the finder.

Moreover, in the imaging state the mirror 515 is in the state ofwithdrawing from the imaging optical path, and the light bundle entersthe solid-state imaging unit 410 through the optical low-pass filter409, constituting the solid-state imaging unit 410, during the shutterunit 514 is opened.

The solid-state imaging unit 410 is bonded to the shutter unit 514constituting a part of the camera body 513. Holding holes 514 a forbonding the solid-state imaging unit 410 are formed in the shutter unit514 at the positions thereof corresponding to the holding holes 102 b ofthe solid-state imaging apparatus. Although the relative positionalrelations of the holding holes 514 a to the holding holes 411 a formedin the optical low-pass filter holding member 411 may not be the same,the relative positional relations may be made to be the same. In thiscase, the optical low-pass filter holding member 411 and the shutterunit 514 can be fixed to the solid-state imaging apparatus all together.

If the bonded side of the solid-state imaging unit 410 has been producedwith accuracy, the optical system of the camera can be configured withaccuracy only by fixing the solid-state imaging unit 410 even when thesolid-state imaging unit 410 is incorporated into the camera body 513,and no adjustments are especially required. That is, the six axisadjustment of the solid-state imaging device to the holding member 102have been completed, and consequently the adjustment of the relativepositional relation between the solid-state imaging device 101 and theoptical viewfinder and the adjustment of the imaging focusing directionare rendered to be unnecessary even when the solid-state imaging unit410 is incorporated in the camera body 513. Consequently, adjustmentsteps can be reduced to a large extent, and inexpensive electronicimaging apparatus can be provided.

As many apparently widely different embodiments of the present inventioncan be made without departing from the spirit and scope thereof, it isto be understood that the invention is not limited to the specificembodiments thereof except as defined in the claims.
